There is porn of it, no exceptions. It is an internet based "rule" derived from a set of generalizations about things you will find on the internet, this one basically referring to how no movie, show, books, or especially children's cartoon is safe from having porn drawn of its characters. It is usually accompanied by people who claim viewing it has "raped their childhoods."
If there is no porn of it, which is of course impossible, it invokes rule35: if there is no porn of it, porn will be made.

Anything and Everything on the internet has been made into a porn. You just have to look hard enough. Only exceptions are as follows:
>Chuck Norris (duh)
>Rule 34 (you can't rule 34 rule 34)
>Abstract objects (you can't rule 34 happiness)

guy1: Have you seen that tentacle porn with Dora the Explorer!
guy2: Yep, still not as bad as Gwen Tennyson blowing an alien while getting fucked by her cousin, mother, and grandpa at the same time!
guy1: Daaaaaammm! rule 34 strikes again!
guy2: Thank god there's no "Chuck Norris fucking Optimus Prime" shit out there.
guy1: You just imagined it, now there is.
guy2: Damn you rule34, damn you!
